WHEELBARROW.

Specification of Letters Patent.

Patented Apr. 13, 1915.

Application filed September 28, 1914. Serial No. 863,915.

To all whom it may concern Be it known that 1, WILLIAM W. BORIGHT, a citizen of the United States, residing at South Framingham, in the county of Middlesex and State of Massachusetts, have invent-ed certain new and useful Improvements in l l heelbarrows, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in wheelbarrows and the object of the invention is to provide a device of this general character having novel and improved means whereby the same may be readily collapsed in order to occupy a minimum amount of space when not in use, so as to save freight rates, and which may be readily assembled into operative condition.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved wheelbarrow whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

in order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in side elevation of a wheelbarrow constructed in accordance with an embodiment of my invention; Fig. 2 is a bottom plan view of the device as disclosed in Fig. 1; Fig. 8 is an enlarged fragmentary sectional view taken through one of the bearings for the wheel supporting axle as herein set forth, illustrating in detail certain features of construction; Fig. 4L is a sectional view illustrating one of the pivotal connections between the back and the base of the wheelbarrow as herein embodied; and Fig. 5 is an enlarged fragmentary sectional view, illustrating the connection between one of the supporting legs and the supporting base as herein set forth:

As disclosed in the accompanying drawings, 1-1 denote side beams or bolsters of predetermined dimensions having their rear extremities formed to afford the hand grasps and said beams or bolsters 1 are tied or connected one with the otherby the cross beams or bolsters 3 bearing against the under surface thereof and secured thereto by the fastening means 1 which also serves as a medium for maintaining the bottom or floor 5 of the device in operative position upon the upper face of the beams or bolsters 1. While any fastening means which will operate with facility may be employed, I prefer to use the means disclosed in the accompanying drawings wherein is disclosed conventional bolts with their coacting nuts with the heads of the bolts substantially flush with the upper face of the bottom or floor 5.

Each of the beams or bolsters 1 at a predetermined point relative to the rear end of the bottom orfloor 5 is provided with a transverse opening? through which is adapted to be projected a shank 8 which is also adapted to be directed through an opening 9 produced in the upper extremity of a supporting leg 10, said supporting leg being positioned inwardly of the beam or bolster 1, as is thought to be clearly shown in the accompanying drawings, and maintained in such position through the medium of the nut or bur 11 adapted to be threaded upon the free extremity of the shank. The opposite end of the shank is angularly disposed, as indicated at 12, and adapted to overlie the outer face of the beam or bolster 1 and terminates in the inwardly disposed angular extremity 1 1 which is adapted to be projected within the opening 15 disposed transversely of the beam or bolster 1 and in alinement with the opening 7, hereinbefore referred to. The end portion 12 of, the shank has a part thereof immediately adjacent the angular extremity 14 offset, as indicated at 16, whereby a loop is afforded to receive the lug 17 depending from a side member 18 whereby a means is afforded for maintaining said side member in operative position.

The back 19 includes the transversely disposed beams 20 having their lower extremities projecting beyond the lower marginal portion of the back and overlying the inner faces of the beams or bolsters 1, and each of such projected portions is provided with an opening 21 adapted to register with an opening 22 disposed transversely of the adjacent beam .or bolster 1 and through which is projected a pivot pin 23, the inner extremity whereof being threaded in order to be properly engaged by the clamping nut 24. The outer extremity of the pin 23 is perpendicularly disposed is of a length to be operatively engaged with the projected portion 25 of the upper longitudinal beam 26 of the back 19 and is disposed a predetermined distance to one side and rearwardly of the adjacent vertical edge of the back whereby a pocket is afforded to receive the adjacent end portion of a side member 18 whereby it will be readily perceived that such side member may be maintained in operative position in an effective and convenient manner.

Pivotally engaged, as at 27, to the under surface of each of the side beams or bolsters 1 at a predetermined point thereon is a resilient strap member 28 having its free extremity of angular formation, as indicated at 29, to snugly receive the lower extremity of a supporting leg 10 and adapted to be detachably engaged therewith through the medium of the threaded member 30 in a manner which is believed to be self-evident. By this arrangement, it will be readily perceived that the supporting leg is braced in operative position yet the parts may be readily collapsed or folded in order to occupy a minimum of space when the device is not in use. It is also to be observed that the legs 10 are tied or connected by the rigid bar 31, as is conventional. The forward extreinity of each-of the beams or bolsters 1 is provided therethrough with a vertical opening 32 and in its under face in close proximity to the opening with a socket 33, the socket is adapted to receive the upstanding lug 3st carried by the heel 35 of the bearing block 86, said heel being also provided with an opening '37 adapted to register with the opening 32 and through which is adapted to be directed the bolt member 38, said bolt member being also disposed through the opening 39 produced in the foot 40 of the forward brace 41 for the back 19, said brace being herein disclosed as a rigid member pivotally engaged with the upper extremity of a transverse beam of the back, as indicated at 4-2, while the foot 40 thereof is disposed at such an angle as to lie snugly upon the upper face of the beam or bolster 1 when in operative adjustment. The bearing block 36 is provided in its inner face with a socket 43 in which is adapted to be mounted an extremity of the shaft let on which is mounted the supporting wheel 4-5 of any ordinary or preferred construction.

From the foregoing description, it is thought to be obvious that a wheelbarrow constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. A device of the character described comprising a wheel supported base, a back pivotally engaged with the base, supporting legs for the base, members for pivotally engaging the supporting legs with the base, each of such members having its outer extremity angularly disposed and overlying the adjacent edge of the base to afford a loop, and side members coacting with the base provided with depending lugs adapted to be received within the loops of the pivot members.

2. A device of the character described comprising a wheel supported base, a back, members for pivotally engaging the back with the base, said members having their outer extremities perpendicularly directed and secured at their outer extremities to the back and disposed in spaced relation with the side edges proper of the back, and side members detachably engaged with the supporting base and adapted to be disposed between the side edges of the back and the perpendicular extremities of the pivot members.

In testimony whereof I hereunto allix my signature in the presence of two witnesses.

WILLIAM W. BORIG'HT.
